The enlarged parathyroid glands of twenty-four patients with primary, and 5 with tertiary, hyperparathyroidism were prospectively studied with MRI, CT, ultrasonography and subtraction scintigraphy prior to surgery. Sensitivities in a prospective study were 63, 60, 53 and 44% for the primary, and 71, 67, 44 and 11% for the tertiary, disease form. On MRI, diseased parathyroids showed the "typical" behaviour of tumours with high signal intensity on T2-weighted and low signal intensity in T1-weighted images. On CT, the lesions were hypodense and on US hypoechoic relative to the thyroid. Retrospective analysis of MRI and CT images yielded sensitivities of 87 and 85%, respectively.
对24例原发性甲状旁腺功能亢进患者和5例三发性甲状旁腺功能亢进患者肿大的甲状旁腺在手术前进行了MRI、CT、超声和减影闪烁扫描的前瞻性研究。在前瞻性研究中，原发性疾病的敏感度分别为63%、60%、53%和44%，三发性疾病的敏感度分别为71%、67%、44%和11%。在MRI上，病变的甲状旁腺表现出肿瘤的“典型”特征，在T2加权像上呈高信号强度，在T1加权像上呈低信号强度。在CT上，病变相对于甲状腺呈低密度，在超声上呈低回声。对MRI和CT图像的回顾性分析得出的敏感度分别为87%和85%。
